MAGAZINE PENCIL.

Application Itiled December 9, 1924. Serial No. 754,736.

To au whom it may concern.'

Be it known that I, RoMoLo NARDI, a citi- F zen of the United States, residing at Camden, in the county of Camdenv and State of New Jersey, have invented new and useful Im rovements in a Magazine Pencil, of whlch the followin is a specification.

My invention re ates to new and useful improvements in a magazine pencll, the primary object of which is to provide in a device ofthis character means for expelling or propelling the lead in that magazine which 1s in operative osition.

Another object of t e invention is to so construct the means which causes any one of the ma azines to be projected into operative position that said means may be used for propelling the lead to expel or project said lead from its magazine. v

A further object of the invention is to rovide a magazine pencil unit which will Ee compact and easily assembled in a pencil casing.

A still further object of the inventionis to provide means for repelling the magazines and also provide means for forcing the pencil casing elements outward or in opposite directions to each other. With these ends in view, this invention consists in the details of construction and combinationv of elements hereinafter set forthand then specifically designated by the claims. l

In order that those skilled in the art to which this invention appertains, may understand how to make and use the same, I will describe its construction in detail, referring by numerals tothe accompanying drawings forming a part of this application, in which Fig. 1, is a side elevation of a pencil embodymg my invention with the parts illustrated in the positions assumed when the pencil is not in use.

Fig. 9, is a fragmentary sectional elevation thereof.

Fig. 10, is a fragmentar sectional'elevation of the upper portion o the pencil showing the manner in which the pencil casing members may be normally forced apart.

Fig. 11, is an enlarge perspective view of the magazine unit.

In carrying out my invention as here embodied, 2 represents the lower pencil casing having its outer end fashioned into cone sha e to provide a restricted opening or out et 3 and enlarged at its inner end to provide a shoulder 4 and a seat 5 while adjacent said inner end are produced a lurality of longitudinal ribs 6 preferably ormed from the metal of the easing andvprojecting bevond the outer surface of said casing.

his lower casing is teleseopically mounted in the upper casing 7 which has a restricted area or ortion of smaller diameter at its inner emi) as indicated at 8 and in this restricted portion are formed a plurality-of guideways 9, said guideways being equa in number to the ribs 6 and said guideways and ribs must be evenly and regularly ositioned so that all of the ribs will pass into the guideways when any one of said ribs is moved into alignment with an one of the guideways. The guideways an ribs are preferably three in number and each one of t em represents the" color of a lead held in the pencil, as for instance, black, red and blue and each of the ribs has the name of its lead delineated adjacent thereto on the lower casing as shown at 10.

The lower casin 2 besides telescoping in the u per casing 'if will rotate therein and there ore with each guidewa 9 is associated an ol'set 11 so that w en the ribs will pass through the guideways 9 and one casing member rotated relative to the other an end of each rib will engage the offset portion l1 and the two casings be held in a retracted position, as plainly shown in Fig. 2.

A cap 12 is mounted on the outer end of the up er casing member and in its axial center 1s Journalled a short shaft 13 having a button or operating means 14 fixed to its outer end while a small spur gear 15 is fixed to its inner end and the latter meshes with another spur gear 16 fixed to the ejectoi 17 also journalled in the cap 12 parallel with the shaft 13.

In the lower casing is mounted the unit shown in Fig. 11 and includes a ring 18 fixed in the seat 5 at the inner end of the lower casing, said ring carrying a plurality of hangers or stirriips 19 having inturned lower ends 20 projecting through suitable longitudinal slots 21 in the lead magazines 22 each having a piece of lead 23 therein, said lead being retained by friction. Between tlie inturned end of a hanger or stirriip within a lead magazine and the inner or upper closed end of said magazine is located a coiled spring 24 so that the action of said spring normally forces the magazine.

inward or upward.

At the inner or upper end of each magazine is a yoke 25 through which passes the lead propelling rod 26 and said yoke is positioned between the collar 27 and sleeve 28 fixed in spaced relation upon the lead propelling rod whereby the latter may revolve in the yoke although the two will slide or move together longitudinally. The sleeve 28 has a socket 29 formed at its upper end which socket is of some polygonal shape, as for instance a slot, a triangle or any other desirable formation to receive the end of the ejector 17 which is similarly shaped and if found desirable the socket and an end of the ejector may be beveled in order to guide the ejector into the socket and permit a certain amount of freedom of movement relative to each other.

The lead propelling rod 26 is threaded as at 30 throughout the major portion thereof for threaded connection with the coupler 31 projecting into a magazine through the lead pusher or propeller 33 located within the magazine and engaging the inner end of a lead.

From the foregoing description it will he seen that when it is desired to use a particular lead the casing members 2 and 7 are rotated relative to each other until a rib 6 with which is associated the designation representing the lead desired is in line with a particular one of the guideways 9, said particular guideway being indicated by some. suitable mark, as for instance a star 34, Fig. 1. These will have aligned the socket magazine carrying the desired lead with the ejector 17 so that when the lower casing member 2 is moved inward the ma ezine associated with the socket engage bythe ejector'will be held stationary and therefore said magazine will assume an operative osition with its lead rejecting through t e opening 3 in the ower or outer end of the casing 2, as shown in Fig. 2. Then by giving the two casing mcmbei's a slight rotation relative to each other the ribs 6 will engage their respective offsets 11 and the two easing members will be held in operative positions.

As all the parts are merely hung on cach other the rotation of a casing member relative to another will cause the selected lead magazine to assume an angle without breaking or being otherwise damaged.

lVhen the parts are in operative positions, as shown in Fig. 3, should the lead in use break it may be propelled outward or expelled by revolving the button 1.4 to transmit motion through the shaft 13, gears 15 and 16, the ejector 17 to the threaded propelling rod 26 the revolving of which will cause the coupler 31 to travel and move the pusher 33 outward thus expelling or propelling the lead untilthe desired amount is exposed.

When the casing members are collapsed so as to move the parts in an operative position the spring in the barrel associated with the' socket engaged by the ejector will he compressed between the outer end ol said magazine and the inturned end 2() of its associated hanger or stirrup l!) and therefore when one casing member is rotated relative to the other to disengage a rib from its offset 11 and re-align the ribs with the guideways 9 said spring will tend to return the parts to their normal positions and since the stirrup is carried by the ring 18and said ring fixed to the lower casing member the latter will be forced outward relative to the upper casing so as to return the two casing members to -the positions shown in Fig. 1.

As the springs 24 are naturally very light due to their relative small size it is desirable, in some cases, to provide an additional means for forcing the casing members apart and utilizing the spring 24 inerely to keep the magazines under tension and preventing them from falling. To illustrate such an arrangement I have shown a spring 35 within the upper casing member bearing against the inner end of the lower casing member and the cap 12, Fig. 10. The; operation of this form of the invention is identical with that previously described and is only an additional means to assist the' springs 24.

Of course I do not wish to be limited to the exact details of construction as herein shown as these may be varied within the limits of the appended claims without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new and useful is:-
